title: Urinary excretion of LATS in a patient with Graves' disease complicated by nephrotic syndrome.
abstract: A case report of a female patient with Graves' disease complicated by nephrotic syndrome with high LATS activity in urinary gamma-globulin is presented. When in the hyperthyroid state with high LATS activity in the serum, she was treated with antithyroid drugs, excess iodine, and finally radioisotopes. Mild hypothyroidism occurred transiently without any significant change in serum LATS activity. Nephrotic syndrome suddenly appeared. Urinary IgG was purified by salting out with ammonium sulfate, DEAE and protein A-Sepharose, and LATS activity in the purified urinary IgG fraction was demonstrated. The specific activity of LATS activity in urinary IgG protein was slightly lower than that of the serum. This case is the first demonstration of LATS activity in urine from a patient with hyperthyroidism and nephrotic syndrome.
